o Minor bugfixes (IPv6, relay):
- Consider IPv6 addresses when checking if a connection is canonical.
In 17604, relays assumed that a remote relay could consider an IPv6
connection canonical, but did not set the canonical flag on their side
of the connection. Fixes bug 33899; bugfix on 0.3.1.1-alpha.
- Log IPv6 addresses on connections where this relay is the responder.
Previously, responding relays would replace the remote IPv6 address with
the IPv4 address from the consensus.

o Major features (Proposal 310, performance + security):
- Implements Proposal 310 - Bandaid on guard selection.
Proposal 310 solves a load-balancing issue within Prop271 which strongly
impact experimental research with Shadow.
Security improvement: Proposal 310 prevents any newly Guard relay to
have a chance to get into the primary list of older Tor clients,
except if the N first sampled guards of these clients are unreachable.
Implements recommendation from 32088.
Proposal 310 is linked to the CLAPS project researching optimal
client location-aware path selections. This project is a collaboration
between the UCLouvain Crypto Group, the U.S. Naval Research Laboratory and
Princeton University.
